Abstract Spin—phonon coupling is important in chromate spinel oxides $A$Cr$_2$O$_4$, but its role in LiFeCr$_4$O$_8$ is not well understood. In this paper, we employ Raman scattering and first-principles phonon calculations to study this material. Ten out of 13 Raman-active modes are well assigned. Notably, no phonon splitting is observed across the structural phase transition due to the remarkably small Grüneisen constants. This observation, in conjunction with the structural data, provides compelling evidence that the structural phase transition in LiFeCr$_4$O$_8$ is primarily driven by the spin-driven Jahn—Teller effect. Interestingly, some Raman modes (at 207~cm$^{-1}$, 306~cm$^{-1}$ and 462~cm$^{-1}$) exhibit unusual linewidth behavior across the temperature range investigated. Furthermore, the Raman spectra in different phases show no magnetic field dependence. These results suggest that phonons couple with short-range spin correlations, offering insights into how spin and lattice degrees of freedom interact in frustrated systems.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
